Can't connect to meeting as user

I have a meeting link, I can connect on a remote computer, but I can't connect on my workstation. I have the latest updates on Windows 10, I use Google Chrome to launch the url, and I've uninstalled and reinstalled the RingCentral app.

I have done a speedtest and show 50 down, 9.5 up, I've disabled the firewall and turned off my AV, still doesn't connect.

I tried calling support, but since I don't have a ring central number they don't care about me. Any ideas why this doesn't work?

Hey john, in order to help, we'll need more information about what's going on. Are you getting an error message? Is your remote computer on a different network than your workstation? If so, there might be something on the workstation network blocking your ability to connect to RC Meetings. Is this just one user who is having an issue, or are multiple people experiencing the same thing? The more details the better! :)

Computer is set up the same as every other computer in our organization. the routers are exactly the same at all sites. Other users in the office can connect, and this one has previously connected, but usually it says trying to connect, then after about 5 minutes it times out, and then says the meeting is over.

Since I'm in IT and not the person who started the meeting, I'm not able to talk to support since they only talk to the account holder. We've confirmed this machine is fully patched. We are using:

1) Does your office have a RingCentral account? Or are you using Meetings because someone outside of your organization would like you to?2) Can you clarify when this started happening? 3) Could you expand on "We've confirmed this machine is fully patched."?

1. As I stated I don't own the Ring central account, if I had it, maybe support would talk to me, however as I don't own the account they don't care. I don't know who owns the account that this meeting is hosted with.

2. We have had 3 meetings that this user is trying to connect to, first one failed, second worked, third failed. All have happened in the past 2 weeks.

3. We use ConnectWise Automate to monitor and control patching in this environment. This computer has all updates that are provided by Windows. Also we are using Chrome. When checking for updates through our tools, or by going into the update tool on the machine, it says there are no other updates. Same for Chrome. There are no pending updates available, and we have rebooted in accordance with how Microsoft requires us to do so. (I have 20 years of experience in IT support roles, it's patched and rebooted)

No errors are presented, just says can't connect, then tries alternate, then says meeting is over. the message is not at all helpful.

The last time we tried, we were waiting for the meeting to start, everything looked correct, then when the organizer signed in, this computer hung, while another computer I was testing on worked. I haven't found any error messages or reasons it wouldn't work.

I spoke with our Tier 3 Support Team and based on the information you provided, it sounds like it's something localized to your network and setup. So! I would check out this article that references the IP Addresses and Ports that need to be enabled for RingCentral Meetings. Maybe that will help! :) I would also double check your firewall settings again to verify that there isn't something there blocking proper communication.

I did see that article, and as I said, it didn't work, then it did work, then it didn't work. Based on the article you quoted, all traffic should be going on port 443, which is unrestricted in our environment. We have tested with several other applications and use that port in our daily tasks, I suspect that something else is going on with your application.

It's too bad you don't have a test meeting server available. I see there is a 3+ year old request for that.

So we had another meeting today and we set up the user's workstation in a DMZ with all traffic allowed in and out, and the meeting worked. Previously we had double and triple checked the article that was referenced above. The only port that is listed is 443.

This article is not complete and should get updated with the full list of ports that need to be opened. We can NOT leave this workstation exposed in this manner. We are legislated to maintain a certain level of security because of the business needs. We can open ports if needed, but opening all traffic in and out of a workstation opens up a bunch of liability and exposes the company to too much risk.

@Saadet, Can you ask the Tier 3 Support team for the actual list of ports that need to be open?
